Which correlation represents the strongest relationship? O a. +.68 O b. -.43 O c. +.37 O d. -.02

The correlation that represents the strongest relationship is:

**a. +.68**

Explanation:
- Correlation values range from -1 to +1.
- The closer the value is to **-1** or **+1**, the stronger the relationship.
- Positive correlations (e.g., +.68) indicate a direct relationship, while negative correlations (e.g., -.43) indicate an inverse relationship.
- A correlation of **+.68** is stronger than the others listed.

Would you like more details on interpreting correlations or how they apply to data?

Here are 5 questions to expand on this:
1. What does a correlation value of +1 indicate?
2. How does a negative correlation differ from a positive one?
3. In what fields are correlations typically used to interpret relationships between variables?
4. What does a correlation of 0 mean?
5. How can you determine if a correlation is statistically significant?

**Tip:** Always remember that correlation does not imply causation.

Learn how to interpret correlation coefficients and identify which value represents the strongest relationship. This example compares four different correlations: +.68, -.43, +.37, and -.02. Understand the concepts of positive and negative correlations, and learn why +.68 is the strongest in this case. Suitable for high school students in Grades 10-12.
